Abstract
Direct numerical simulations of a vortex pair embedded in a stable atmospheric boundary layer are presented. The effects of various crosswind conditions are studied. These computations demonstrate the creation of secondary vortices for the range of Reynolds numbers (3770≤Rer≤). The physics of wake vortex interactions with the ground for different values of crosswind are discussed. The redistribution of vorticity between the atmospheric boundary layer and the vorticity induced by the primary vortices may explain the vortex tilting phenomenon. A parametrization of the effect of crosswind on the minimum altitude reached by the two vortices is given.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
